Accordingqto "another: way of carrying out the inventionyan ektra @lymn-iiliesinaWbe provide,

these sole'ly or primarily i 01-- car1'ying; advertising matter m which lattenease -the ply or plies i-la'st mentioned may be nested between the plies participating in the book mark structure per se, may be thus nested have one or more subdivisions each bounded by a fold line marking the separation of one such subdivision from an adjoining one, and may, also, in addition to or in lieu of having one or more folds, be slidably carried by the book mark structure per se.

Referring now to the drawings in detail:

In Fig. 1, two plies 25 and 26, stapled together as at 21, are parts of a unitary strip or sheet; this structure for straddling a corner of a book page.

Fig. 2 shows two plies 28 and 29, also parts of a unitary strip or sheet, but stapled together as at 36 parallel with and adjacent to the fold between said plies, rather than at an angle to such fold as in Fig. 1, this structure for straddling a book page at, if desired, other than a corner thereof.

Fig. 3 shows two integral plies 30 and 3|, stapled as at 32, but with each of such staples, while adjacent the fold between the two plies, perpen dicular to such fold.

Fig. 4 shows a structure like that of Fig. 2, with the staples as at 33, but with each of two plies 34 and 34- separate pieces.

Fig. shows a structure wherein the staples, 35, are placed as in Fig. 2, in regard to two plies 36 and 31 parts of a unitary strip or sheet as in Fig. 2, but wherein these staples also hold in place a third ply 38 integral with the ply 31 but separated from the latter by a line of fold ex tending at an angle to the line along which the staples are applied.

Fig. 6 illustrates a book mark somewhat similar to that of Fig. 1, but, as in Fig. 5, including a ply 39, in the form of a separate piece, additional to two plies 4| and 42 integral with another piece; with all these plies stapled together as at 43- In Fig. 7, an arrangement is shown comprising four plies 44, 45, 46 and 41, all parts of a single unitary strip, with the plies 44 and 46 stapled together as at 48. The plies 45 and 41 are free end extensions, respectively, from the plies 44 and 46, each such extension ply separated from the main ply 44 or 46 by a line of fold as shown.

Fig. 8 shows a book mark having two outer plies 49 and 50, each a separate piece, with a longer ply 5|, also a separate piece, inserted therebetween, and with all the plies stapled together as at 52. Such insert 5| may carry on both sides extensive advertising matter; and along the. length of the insert 5| it may be provided with fold lines as at 53 and 54, so that, while it may be extended as shown, .it may be folded on itself for receipt when in such folded condition between the plies 49 and 56.

In Figs. 9 and 10, an embodiment is illustrated having a pair of plies 55 and 56 forming parts of a unitary strip, and also a longer ply 51, all three of these plies stapled together as at 58,. The ply 51, an addendum analogous to the ply 5|, is also provided with fold lines as at 59 and 60, so that,

as shown in Fig. 10, the ply 51 may be withdrawn In Figs. 13 and '14, two plies 61 and 68, which may be separate pieces, but are here shown as parts of a unitary sheet folded as at 69, are stapled together as at 10. Along such fold line and between the two staples said sheet is slotted as at 1|. An addendum 12 for carrying advertising matter is here shown as in the form of a slide ply 12, having at one end a T-bar portion 13 to prevent accidental loss of the slide ply by way of the slot 1|, and having at its opposite end a pull-tab enlargement 14.

With the parts normally as in Fig. 13, even when the device is in use as a book mark, the tab 14 does not objectionably project; but it sufiiciently projects to offer itself as a convenient pull portion to be manually engaged for removing the book mark. The first part of a pull on the tab arranges the parts as in Fig. 14, to display the advertising matter on the addendum 12, and further continuance of the pull acts through the portion 12 of said addendum, to free the book mark from a book page.

Fig. 15 shows a modification of the structure just described, in which the slide ply addendum 15 for carrying advertising matter and for having the utilities mentioned above in connection with the addendum 12 is shown as of a somewhat difierent shape from that of the addendum 12, and in which the slot 16 corresponding to the slot 1| is remote from the staples 11. The slot 16 is placed along a fold 16 subdividing one ply outward from the addendum 15 into a main outer portion 18 and a lesser inturned portion 19, these two plies being integral with a ply 89 also outward from said addendum.

In Figs. 16 and 1'1, a structure is shown which also includes a slide ply addendum 8| guided, for retraction as in Fig. 16 and for projection as in Fig. 17, by means of a slot 82 cut through 2. ply 83 stapled to another ply 84 as at 85. The plies 83 and 84 may be separate pieces, or, as here shown, parts of a single'unitary strip. The addendum 8| has a T-bar bottom enlargement 86, for a purpose similar to that of. the portion 13 of Fig. 13; while the main upper portion of the addendum 8| has two subdivisions, 81 and 88, separated by a fold line 89, so that the advertising medium provided by said addendum per se may not only be slidingly withdrawn but also unfolded for displaying its advertising message. The arrangement is such, as will be noted in Fig. 10, that when said addendum is retracted, the device is of four ply thickness.

Figs. 18 and 19 show an arrangement incorporating an addendum like the addendum 51 of Fig. 10, this stapled as at 9| within a book mark like that of Figure 6; with here the plies which correspond to the plies 39, 4| and 42 of the last-named structure marked, respectively, 92,93 and 94.

Referring, finally, to the embodiment of Fig. 20, two slide ply addenda and 96 are provided, each like the addendum 15 of Fig. 15, there being here present for the addendum 95 a slot 91 and for the addendum 96 a slot 98. The slot 98 is along a fold line 99 corresponding to the fold line 15 16 with the ply subdivisions and lllll corresponding, respectively, to the parts 19 and 18. The ply element H32 corresponds to the ply 00, but said element is a ply subdivision the other and complementary subdivision 33- of which is a lesser one inturned as is the ply subdivision 19!, to allow placement of the slot 97 along the fold line between said subdivision 5%! and 103. The two members l00l0l and l02--i03 may be separate pieces, but as here shown they are parts of a unitary strip folded as at 194 and stapled as at H15.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A book mark incorporating a pair of plies of sheet material arranged for frictionally engaging between them the opposite sides of the page of a book, said plies made of a relatively thin, flexible material which has an inherent resiliency characteristic of a fairly dense thin cardboard, and means securing said plies together along a bounding edge of the book mark to stiffen said resilient characteristic of each at i an elongate region alongside said line, there being an additional ply coupled to one of the two first-named plies to provide a two ply structure stiifer than the structure constituted by the other flexible material which has an inherent resil- 4 iency characteristic of a fairly dense thin cardboard, and means securing said plies together along a bounding edge of the book mark to stiffen said resilient characteristic of each at an elongate region alongside said line, there being an additional ply coupled to one of the two firstnamed-plies to provide a two ply structure stiffer than the structure constituted by the other of the two first-named plies, said additional ply being fold-line joined to that one of the two firstnamed plies with which said additional ply forms said two ply structure.

3. A book mark incorporating a pair of plies of sheet material arranged for frictionally engaging between them the opposite sides of the page of a book, said plies made of a relatively thin, flexible material which has an inherent resiliency characteristic of a fairly dense thin cardboard, and means securing said plies together along a bounding edge of the book mark to stiffen said resilient characteristic of each at an elongate region alongside said line, each of said plies being of quadrilateral outline to provide space at the outer side of each ply for carrying an advertising message, said bounding edge being one of the sides of said quadrilateral, said plies being also secured together along an adjoining side of said quadrilateral.

4. An advertising addendum for a book mark having a pair of adjacent plies for engagement over the top edge of a book leaf, comprising a single strip of material imprinted with advertising matter and folded upon itself substantially intermediate of its ends to provide adjacent leaves one of which is longer than the other, one of the plies being formed adjacent one end with a slot of a length corresponding to the width of said strip of material, said folded strip of material being positioned between said plies with its shorter leaf facing the ply formed with said slot, said folded strip of material having the junction of its leaves extended from said slot providing a grip for pulling said strip of material outward through said slot, and means on the longer leaf of said folded strip of material to restrain said folded strip of material against further outward movement when said folded strip has been pulled to a position in which said shorter strip is completely withdrawn from said slot.

5. An advertising addendum for a book mark having a pair of adjacent plies for engagement over the top edge of a book leaf, comprising a single strip of material imprinted with advertising matter and folded upon itself substantially intermediate of its ends to provide adjacent leaves one of which is longer than the other, one of the plies being formed adjacent one end with a slot of a length corresponding to the width of said strip of material, said folded strip of material being positioned between said plies with its shorter leaf facing the ply formed with said slot, said folded strip of material having the junction of its leaves extended from said slot providing a grip for pulling said strip of material outward through said 'slot, and means on the longer leaf of said folded strip of material to restrain said folded strip of material against further outward movement when said folded strip has been pulled to a position in which said shorter strip is completely withdrawn from said slot, said restraining means comprising ears extended laterally from the end of said longer leaf remote from the junction of said leaves for engaging the material of the said one ply at the ends of said slot.
